Ru wiki bitcoin minerals
Mining is the process of ru wiki bitcoin minerals transaction records to Bitcoin's public ledger of past transactions. This ledger of past transactions is called the block chain as it is a chain of blocks. The block chain serves to confirm transactions to the rest of the network as having taken place.
Ru wiki bitcoin minerals nodes use the block chain to distinguish legitimate Bitcoin transactions from attempts to re-spend coins that have already been spent elsewhere. Mining is intentionally designed to be resource-intensive and difficult so that the number of blocks found each day by miners remains steady. Individual blocks must contain a proof of work to be considered valid. This proof of work is verified by other Bitcoin nodes each time they receive a block.
Bitcoin uses the hashcash proof-of-work function. The primary purpose of mining is to allow Bitcoin nodes to reach a secure, tamper-resistant consensus of which private keys control which bitcoins. This both serves the purpose of disseminating new coins in a decentralized manner as well as motivating people to provide security for the system.
Bitcoin is designed to introduce new bitcoins into the system in a predictable manner see controlled supply. This makes a challenging problem - how is the issuance of currency kept at a fixed amount of time regardless of the amount of effort put into mining? Mining a block is difficult because the SHA hash of a block's header must be lower than or equal to the target in order for the block ru wiki bitcoin minerals be accepted by the network. This problem can be simplified for explanation purposes: The hash of a block must start with a certain number of zeros.
The probability of calculating a hash that starts with many zeros is very low, therefore many attempts must be made. In order to ru wiki bitcoin minerals a new hash each round, a nonce is incremented. See Proof of work for more information. The difficulty is the measure of how difficult it is to find a new block compared to the easiest it can ever be. It is recalculated every blocks to a value such that the previous blocks would have been generated in exactly two weeks had everyone been mining at this difficulty.
This will yield, on average, one block every ten minutes. As more miners join, the ru wiki bitcoin minerals of block creation will go up. As the rate of block generation goes up, the difficulty rises to compensate which will push the rate of block creation back down.
Any blocks ru wiki bitcoin minerals by malicious miners that do not meet the required difficulty target will simply be rejected by everyone on the network and thus will ru wiki bitcoin minerals worthless.
When a block is discovered, the discoverer may award themselves a certain number of bitcoins, which is agreed-upon by everyone in the network. Currently this bounty is 25 bitcoins; this value will halve everyblocks. Additionally, the miner is awarded the fees paid by users sending transactions. The fee is an incentive for the miner to include the transaction in their block. In the future, as the number of new bitcoins miners are allowed to create in each block dwindles, the fees will make up a much more important percentage of mining income.
